Answer 1

You need to tell javac which version of java you are using. This is done with the -source and -target parameters. If you are using Maven this can be set in your pom.xml with the compiler plug-in if you're using Ant this can be set in the javac Task.

Answer 2

您可以使用-source手动设置源版本兼容性

javac -source 5 YourFile.java

Answer 3

javac -source 7 YourFile.java

将是这个问题的解决方案
